'SUIPLEIVIEIITAL TIRE.

Application filed. July 17, 1922. Serial as.

State of Kansas. have invented certain new and usetul Imprm'ements 1inSupplemental Tires; and I do declare the following to be a full. clear,and exact description of the invention. such as will enable othersskilled in the art to which it appertains to make and use the same.reference being had to the accoi'upanying drawings. and to the figuresof reference marked thereon, which-form a part of this specification. I

This invention relates to a supplemental tire to be applied about theperimeter ot a tractor wheel.

Tractor wheels usually are supplied with transverse cleats or shoeswhich cut into' the ground so as to increase traction when the tractoris moving over the field. These cleats or shoes are detrimental to the.roadsurtace of the highway as they alsocut nto and frequently through.the road surface which is obviously objectionable. lnasmuch as tractorstations are established. in towns and cities and the tractor is used onthe farm, it is apparent that unless some means is provided torprotecting the road from contact with cleats or shoes. the tractors willhave to be transported from the distributing depot to the farm bytrucks. It isnot often convenient to so transport the tractors onaccount of the distances. etc.. and because of lack of conveniences. I

My invention contemplates a supplemental wheel the or guard which may bereadily applied to a tractor wheel so as to cover the cleats so that theroad will not be out when the 'ractor is being driven from its distrib-"of the guard or supplemental tire being broken away to show the mannerof fastening the supplemental tire or guard.

Fig. '2. a tragmentary cross sectional viewthrough the normal tire andthesuppleniental tire. the fastening means being shown in elevation.

he invention is shown applied to a tractor wheel of conventional design.The. tractor wheel isshown as comprising a ring or tire -1. havinginturnede'dge Flanges 2 and/3 whereby the ring or tire 1 is in the Formot a channel. The ring or vtire l is connected to an appropriate. hublby spokes 5 and across the periphery of the tire are all le-shapedcleats 5, having outstanding ed s which. bitein'to the ground when therehicle is propelled. it these cleats -'or shoes which are detrimentalto highway surtaces and my invention contemplates means tor protectingthe roadway "from them.

i supplenwntal tire or guard. is shown as comprising two similarcircular channelshaped mei'lihers 8 and 9, the widths of which are lessthan the widths of tire 1. The inturned flanges l0 and 11 for the memberS, and 12 and 13 for the member 9 are novidecl with holes. all ot'. theholes in all olf the llangcs being designated 'l-l. These holes areadapted to receive the hook sl1a ')ed ends o'l" the. connecting links orcoupling meniljlers to which tl asten the members 8 and ti to tire l.The members 16 are curved outwardly to the ends 17 distant from thehooks l5. U-shaped jaws are provided which can slide on the shank l9 andreceive the flanges Q and 3. depending upon which side oi the wheel theflanges 16 are arranged. li hen the hook is in an opening 14:, acomplementary jaw 18 receives the flange (either 2 or 3), the nut 20 onthe end 17 can be screwed to draw the members 8 and 9, as the case maybe. tight against the edges of the cleats t5, and a direct pull will beexercised on the member 8 or flbecause the shank 19 lies parallel withflange received by the jaw 18 as will be apparent by ret'erring to Fig.2..

Since the supplemental tire or guard. consisting mainly of the twomembers 8 and 9 In actual practice I find that aboiiit six connectinglinks 0:: coupling 16 will suffice for each member 8 and 9 that istwelve con nectinglinlcs are recoinmended for awheel;

two at each end of each section 8 and 9 and two at the center, makingthreeon a side. I do not Wish to be limited, however, to any particularnumber of links nor necessarily to the exact details shown. v a From theforegoing it Will-h i-apparent that the supplemental the guard can beremlily attached to and detached from the tractor Wheel and thatapplication oi. the supplemental. tire will amply protect the surface ofthe highway from being cut by a clcat of the Wheel. V lla-t I claim anddesire to secure by Letters Patent is:

1'. The combination with a a ring mounted about the tire and restingupon the cleas to protect the cleats from contact with the ground, linkshaving;-

xructor Wheel haying transverse cleats on the tire thereof,

tire to secure the ring rigid with respect to the cleats. V i

2. Incombinatiom a tractor wheel] having a channel-shaped tire.transverse cleats across the periphery of the tire, a ring mounted onthe cleats and concentric with the tire, link members connected to thering,

and flange-engaging an's on the link members, the jaws being cngageablewith the flanges of the tire.

3. The combination with a tractor \Yl'lQCl having a tire provided withtransverse cleats across its periphery, thetire consisting of a channelwith flanges bent inwardly; a channel-shapedring for attachment to theWheel so that the flanges of the ring bear on the cleats. and. menus forattaching: the
